18125 Brianwilson           Discovered 2000 July 22 by J. Broughton at Reedy Creek Observatory.
Californian songwriter and record producer Brian Wilson (b. 1942) contributed to 1960s pop culture, with songs like Fun Fun Fun, exemplifying the pastimes of modern teenage life, through the Beach Boys' pop group harmonies, giving out very good vibrations indeed.
